Spatial Hearing AI and contextual voice AI for OEM devices
Locates sound sources and separates overlapping speakers so a device can pick out the voice it needs, even in reverb-heavy or crowded rooms.
Adds contextual awareness so devices recognize who is talking and interpret intent rather than matching keyword phrases.
Runs on the device instead of the cloud, cutting latency and keeping raw audio local for privacy and offline reliability.
Supports hands-free, multi-seat in-car interaction where several passengers may speak at once and road noise is constant.
Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
